Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
Mountain range – Geographic area containing several geologically related mountains; Nunatak – Landform within an ice field or glacier; Proglacial lake – Lake formed by the action of ice; Pyramidal peak, also known as Glacial horn – Angular, sharply pointed mountainous peak; Outwash fan – Type of sediment deposition by a melting glacier
Sedimentation is the deposition of sediments. [1] It takes place when particles in suspension settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or ...
Deltas are typically classified according to the main control on deposition, which is a combination of river, wave, and tidal processes, [19] [20] depending on the strength of each. [21] The other two factors that play a major role are landscape position and the grain size distribution of the source sediment entering the delta from the river.
That is, deposits laid down by volcanism or by deposition of sediment derived from weathering detritus (clays, sands etc.). This includes all its fossil content and the information it yields about the history of the Earth: its past climate, geography, geology and the evolution of life on its surface.
The hydrothermal deposition of economically important metals in the formation of ore bodies or "lodes". mineralogy miogeosyncline A geosyncline in which volcanism is not associated with sedimentation, or the non-volcanic part of the orthogeosyncline located near the craton. Mohs scale of mineral hardness. Also simply called the Mohs scale. molasse

Geology (from Ancient Greek γῆ (gê) 'earth' and λoγία () 'study of, discourse') [1] [2] is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time.
